31、ial properties are typically tested tovalidate a formulation; they are not routine quality assurance tests. Usersrequiring such testing for quality assurance purposes should insert thesecriteria in their project specifications.6. General Requirements6.1 WorkmanshipThe pipe and fittings shall be homo

32、ge-neous throughout and be as uniform as commercially practicalin color, opacity, and density. The pipe walls shall be free ofcracks, holes, blisters, voids, foreign inclusions, or otherdefects that are visible to the naked eye and that may affect thewall integrity.
